The car’s at the d(st)ealership right now and I have to bear three days without it. I’ve checked out shops who carry a whole set of the engine wiring harness and it seems that I’m fucked. The prices all range from $800 to $1200 as initially quoted. Not really something that’s practical and reasonable for a project on a budget.

So I just took the alternative of having them restore the engine wiring harness according to the genuine schematic. The dealership’s estimate is that it’d take three days but would be worth a lot less. But since I’m only having the wiring re-done, they can’t guarantee that the bucking and jerking would go away. But having the wiring re-done to the real schematic would allow the ECU to get accurate readings. I’m holding off replacing the AAC valve assembly for now.

What worries me is the error code that shows that possibly the ECU’s damaged. I’m also hoping that the wiring would solve that. They said that it’s impossible to tell until the wiring’s redone but it’s a $160 (yeah, they upped the cost of having the wiring redone) shellout just to get a confirmation.

If all else fails, I’m having the car converted to carb. Though we’re still researching if this is possible with the GA16DE engine.
